Speedometer Malfunction: Procedure

1. Check if a CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM [12/2011 - ] .
   RESULT
   
   

   Result	Proceed to
   CAN communication DTC is not output	A
   CAN communication DTC is output	B

B → See step   10 

A: Go to next step 

1. Use the Active Test to check the operation of the speedometer. Refer to DATA LIST / ACTIVE TEST [12/2011 - ] .
   COMBINATION METER
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Speed Meter Operation	Speedometer	0, 40, 80, 120, 160, 200, 240 (mph)*1	Acceptable range (mph): [Control range → Speedometer display] 40 → 39.2 to 42.4 80 → 79.8 to 83.4 120 → 120.6 to 124.4 160 → 161.3 to 165.3 Confirm that the vehicle is stopped with the engine idling.
   		0, 40, 80, 120, 160, 200, 240 (km/h)*2	Acceptable range (km/h): [Control range → Speedometer display] 40 → 38.6 to 43.1 80 → 78.8 to 84.3 120 → 119.5 to 125.5 160 → 160.1 to 166.6 200 → 200.6 to 207.6 240 → 241.4 to 248.4 Confirm that the vehicle is stopped with the engine idling.

   1. *1: for U.S.A.
   2. *2: for Canada

   OK

   Speedometer indication is normal.

NG → See step   9 

OK: Go to next step 

1. Use the Data List to check if the speedometer is operating properly. Refer to DATA LIST / ACTIVE TEST [12/2011 - ] .
   COMBINATION METER
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Vehicle Speed Meter	Vehicle speed/Min.: 0 mph (0 km/ h), Max.: 255 km/h (158 mph)	Almost same as actual vehicle speed	-

   OK

   Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).

NG → See step   8 

OK: Go to next step 

1. Use the Data List to check the wheel speed. Refer to DATA LIST / ACTIVE TEST [12/2011 - ] .
   ABS/VSC/TRAC
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   FR Wheel Speed	Vehicle speed/Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)	Almost same as actual vehicle speed measured using speedometer tester	-
   FL Wheel Speed	Vehicle speed/Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)		-
   RR Wheel Speed	Vehicle speed/Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)		-
   RL Wheel Speed	Vehicle speed/Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)		-

   OK

   Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).

NG → See step   6 

OK: Go to next step 

1. Replace the combination meter assembly with a new or normally functioning one. Refer to REMOVAL [12/2011 - ] .

   OK

   The operation of the speedometer returns to normal.

NG → See step   7 

OK → END (COMBINATION METER ASSEMBLY WAS DEFECTIVE)
